Logos on uniform

[stevegarbs]

Hello, I am a football official who moonlights as a softball coach (and perhaps, someday in the future, an umpire). I am hoping the expert minds here can help me with a uniform question.

Is there any prohibition against including the image of a softball in a team's logo? I know there are such rules in MLB, and football has rules against penalty flag-colored pads and gloves, but I cannot find anything in the ASA rules about the subject. I am interested in learning if any of the youth-oriented rule codes ban the inclusion of such an image. Thanks in advance.
